Definitions

  • the invention relates to the field of manufacturing composite materials using fibers as a reinforcing material and plastic as a base material, which comprises carbon fiber, glass fiber, aramid fiber, boron fiber and the like.
  • the fiber portion of the composite material as a reinforcing material is mainly a woven fabric in which a fiber filament bundle is warp-weaved by a liquid resin, a liquid resin hand paste, an injection or a pre-dip method, and a thermosetting composite material, but
  • the high flexural wave generated by the warp and weft interlacing of the woven fabric reduces the fiber ratio in the volume of the composite material, and the bending of the filament reduces the tensile strength.
  • the composite product is generally formed by stacking a plurality of woven fabrics, and the shear resistance between the layers is poor.
  • the warp and weft interwoven woven fabric has almost no tensile strength in the diagonal direction between the warp and weft.
  • the various non-woven fabrics of the prior art are not suitable for use in the composite materials, and mainly have problems such as poor tensile strength, low fiber ratio in the volume of the composite material, and difficulty in infiltrating the fluid substrate, such as fiber length.
  • the invention solves the reinforcing material in the composite material with the fiber as the reinforcing material and the plastic as the base material, the defect problem of the fiber filament bundle warp and weft interlaced cloth, and the interlacing of the interlaced warp and weft
  • the flexor wave height increases the specific gravity of the tow in the unit volume, so that the fabric has tensile strength in the diagonal direction of the warp and weft direction, so that the fluid substrate in the composite material is easily injected into the layers of the infiltrated fiber tow layer during the processing. Increase the interlaminar shear force.
  • a non-woven fabric characterized in that: a non-woven fabric in which filaments are arranged in a flat surface and is bonded by a plurality of flat flat surfaces, the flat surface further comprising a plurality of single-group tows arranged in parallel and closely arranged.
  • One or more sets of tow positions are left with empty gap positions to form a unit group, and a plurality of unit groups are cyclically arranged into a flat surface single layer, and the single layers are respectively arranged in a warp direction single layer and a weft direction single layer.
  • the single layer and the single layer in different directions are bonded by a drop-shaped adhesive material, and are superposed and bonded into a multilayer nonwoven fabric by a single layer in different directions.
  • the single set of tows is characterized by a single wire, a chopped wire, and a mixed yarn of different filaments, a mixed yarn and a mixed yarn thereof.
  • the short cut wire is placed.
  • the chopped strands are characterized by a straight shape, a curved shape, a spiral shape or a mixture of two or more thereof.
  • the drop-shaped adhesive material further characterized by a bead-shaped, mist-like adhesive material.
  • the multilayer nonwoven fabric is characterized in that the single layer stacking order in different directions is freely set.
  • the multilayer body is further characterized by adding a single layer in a certain direction or subtracting a single layer in a certain direction.
  • the multi-layer non-woven fabric further includes a reinforcing material suitable for a composite material using a fiber as a reinforcing material and a plastic as a base material.
  • the multilayer nonwoven fabric is further characterized in that a single layer in each direction is bonded by a prepreg process.

  • the embodiment of the present invention is applicable to a composite material in which a fiber is used as a reinforcing material and a plastic is used as a substrate.
  • the reinforcing material is made of carbon fiber, and the carbon fiber is a bundle of carbon fiber filaments.
  • the tow 1 is arranged in a plurality of sets of tow planes, wherein the position of the tows of 1 or more sets is left with a gap position 2 to form a unit group, and the plurality of unit groups are cyclically arranged into a flat surface single layer. .
  • each layer unit group A curved chopped aramid fiber short yarn is placed in the empty gap position, and any one of the two layers of the single layer has a flat surface other than the empty gap position, and the same short wire is placed in a smaller amount than the empty gap position.
  • a single layer in either direction, depending on the application, may be added as a single layer or a single layer, and then sprayed into a droplet bond between the layers using a spray-type adhesive material to form a multilayer nonwoven fabric.
  • the tow comprises a wire, a fiber filament, a fiber chopped wire or a mixture of two or more thereof.
  • the multilayer nonwoven fabric is also suitable for use in a general-purpose nonwoven fabric for general use, and includes a nonwoven fabric having a tensile strength requirement for a diagonal between the warp and weft directions of the nonwoven fabric.

Abstract

La présente invention concerne un non-tissé fabriqué par liaison de multiples couches ensemble ; chaque couche utilise une pluralité d'ensembles uniques de câbles (1) disposés étroitement, et des positions d'espace vide (2) sont disposées à une certaine distance ; un brin coupé est placé entre la position d'espace vide (2) de chaque couche et sur la surface plate restante d'une autre couche ; des couches de direction de chaîne et de trame (3, 4) sont utilisées ; la couche gauche (5) et la couche droite (6) de la diagonale entre les directions de chaîne et de trame sont constituées de couches superposées et liées ; ledit non-tissé a une proportion accrue de câbles (1) par volume unitaire ; chaque diagonale entre la chaîne et la trame a une résistance à la traction ; la force de cisaillement interlaminaire est augmentée, de telle sorte que l'invention est appropriée pour des matériaux renforcés par des fibres et des matériaux de renforcement pour des matériaux composites à base de plastique ; elle peut également être utilisée à des fins diverses, et est un non-tissé ayant une résistance à la traction élevée, une forte résistance à la déformation, une forte résistance au cisaillement interlaminaire et une bonne souplesse.
